Opposite card slot side forms clamping gap.
When circuit board is inserted into card slot, card column high spot is pushed by circuit board, and card column makes card to card slot outer elastic deformation
It connects gap width to become larger, so that card slot can be inserted in the circuit board of different-thickness, be fixed in clamping gap location using card column protrusion
Firmly circuit board.
Preferably, the card slot width is greater than circuit plate thickness, and the clamping gap width is less than circuit plate thickness, is formed
Up-narrow and down-wide circuit board insertion groove.
Preferably, the maximum width of the card slot is 2.0mm, and the minimum widith in the clamping gap is 0.5mm.
Preferably, the card column protrusion lower inside is inclined-plane, and inside upper part is vertical plane, the circuit of vertical plane and insertion
Plate forms face contact.The lower inside of card column protrusion is inclined-plane, so that circuit board is easier to push card column to card when being inserted into card slot
Slot outer elastic deformation facilitates circuit board to be inserted into card slot.The inside upper part of card column protrusion is vertical plane, the electricity of vertical plane and insertion
Road plate forms face contact, and under elastically-deformable reaction force, circuit board is fixed by card column protrusion, bigger due to having
It is clamped contact surface, so that having better fixed function to circuit board, stability is high, and shock resistance is good.
Preferably, upper inside wall or the cup body back side of cup body is arranged in the card slot, and symmetrically arranges along cup body radially opposite sides
The position of column, card slot setting determines that some card slots needs are arranged in cup body according to the shape of different radiator cups
Wall, circuit board are inserted perpendicularly into card slot；And some need for card slot to be arranged in the back side of cup body, the laterally inserted card slot of circuit board.
Preferably, circuit board is inserted into from the maximum width of the card slot to clamping gap location.
Preferably, the card slot is integrally formed, and radiator cup is integral with card slot.
Compared with prior art, the beneficial effects of the present invention are: separating shape with cup body inner wall by card slot other end side
At card column to card slot outer elastic deformation, cooperate the vertical plane and circuit board side face contact of card column protrusion, so that insertion blocks
The circuit board installation fixation of slot is more stable, and shock resistance is good, while making to can be adapted for market with a LED lamp heat sink cup body
The circuit board of upper majority different-thickness.

Specific embodiment:
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of LED lamp heat sink with variable-width circuit board slot, as shown in Figs. 1-5, including cup
Body 1, the card slot 2 as insertion circuit board, described 2 one end of card slot is fixedly connected with cup body 1,2 other end of card slot wherein one
Side is separated with cup body 1 to form card column 3 or 2 other end two sides of the card slot separate each self-forming card column 3 with cup body 1；It is described
The end side of card column forms clamping gap 5 in protrusion 4, described raised 4 and opposite 2 side of card slot.
Common circuit plate thickness is set as 0.5mm in 0.8-1.6mm, the minimum widith for being clamped gap 5 in the market, this
Width be less than the general minimum thickness LED lamp circuit plate of existing market, so as to block general minimum thickness LED light circuit
Plate, the maximum groove width of card slot 2 is 2.0mm, which can be inserted the general maximum gauge LED circuit board of existing market, work as circuit board
When being from bottom to top inserted into card slot 2, since clamping gap width is less than board side hem width degree, pushed away at card column protrusion 4 by circuit board
It squeezes, card column 3 is to 2 outer elastic deformation of card slot, and the outside elastic deformation of card column 3 makes clamping 5 width of gap become larger, so that same
Money LED lamp heat sink cup body is suitable for the circuit board of most different-thickness in the market；2 material of card slot is elastic material, excellent
Plastics are selected as, there is certain toughness, when circuit board is extracted, card slot 2 can restore original shape automatically.
1 back side of upper inside wall or cup body of cup body 1 is arranged in card slot 2, and is symmetrically arranged along 1 radially opposite sides of cup body, card slot 2
The position of setting determines that some card slots 2 need to be arranged in the inner wall of cup body 1, electricity according to the shape of different radiator cups 1
Road plate is inserted perpendicularly into card slot 2；And some relatively thin radiator cups 1 need for card slot 2 to be arranged in the back side of cup body 1, circuit board
Laterally inserted card slot 2.
The lower inside of card column protrusion 4 is inclined-plane, so that circuit board is easier to push card column 3 to card slot 2 when being inserted into card slot 2
Outer elastic deformation facilitates circuit board to be from bottom to top inserted into card slot 2；The inside upper part of card column protrusion 4 be vertical plane, vertical plane with
The circuit board of insertion forms face contact, and under elastically-deformable reaction force, circuit board is fixed by card column protrusion 4, so that
There is better fixed function to circuit board, stability is high, and shock resistance is good.
